iPhone开发之地图定位（CoreLocation和Mapkit框架）简易编程

下面介绍的时地图定位和位置反编码

//

// AppDelegate.h

// LocationDemo

//

#import

#import

#import

@interface AppDelegate : UIResponder<</span>UIApplicationDelegate,CLLocationManagerDelegate,MKReverseGeocoderDelegate>

@property (strong, nonatomic) UIWindow *window;

@end





//

// AppDelegate.m

// LocationDemo

//

#import "AppDelegate.h"

@implementation AppDelegate

- (void)dealloc

{

[_window release];

[super dealloc];

}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];

// Override point for customization after application launch.

self.window.backgroundColor = [UIColor whiteColor];

[self.window makeKeyAndVisible];



CLLocationManager *locationManager = [[CLLocationManager alloc] init];

//设置过滤信息

// [locationManager setDistanceFilter:<#(CLLocationDistance)#>]

//设置定位的精度

[locationManager setDesiredAccuracy:kCLLocationAccuracyNearestTenMeters];



locationManager.delegate = self;



//开始实时定位

[locationManager startUpdatingLocation];



return YES;

}

//实时定位调用的方法, 6.0过期的方法

#pragma mark - CLLocationManager delegate

- (void)locationManager:(CLLocationManager *)manager

didUpdateToLocation:(CLLocation *)newLocation

fromLocation:(CLLocation *)oldLocation {



CLLocationCoordinate2D coordinate = newLocation.coordinate;

NSLog(@"经度：%f,纬度：%f",coordinate.longitude,coordinate.latitude);



//停止实时定位

[manager stopUpdatingLocation];



//计算两个位置的距离

// float distance = [newLocation distanceFromLocation:oldLocation];

// NSLog(@"%f",distance);





//------------------位置反编码---5.0之后使用-----------------

CLGeocoder *geocoder = [[CLGeocoder alloc] init];

[geocoder reverseGeocodeLocation:newLocation

completionHandler:^(NSArray *placemarks, NSError *error){



for (CLPlacemark *place in placemarks)
{

NSLog(@"name,%@",place.name); // 位置名

NSLog(@"thoroughfare,%@",place.thoroughfare); // 街道

NSLog(@"subThoroughfare,%@",place.subThoroughfare); // 子街道

NSLog(@"locality,%@",place.locality); // 市

NSLog(@"subLocality,%@",place.subLocality); // 区

NSLog(@"country,%@",place.country); // 国家

}



}];



//----------------------位置反编码--5.0之前的使用-----------------

MKReverseGeocoder *mkgeocoder = [[MKReverseGeocoder alloc] initWithCoordinate:coordinate];

mkgeocoder.delegate = self;

[mkgeocoder start];



}

//6.0之后新增的位置调用方法

//- (void)locationManager:(CLLocationManager *)manager

// didUpdateLocations:(NSArray *)locations {

// for (CLLocation *location in locations) {

// NSLog(@"%@",location);

// }

//

// //停止实时定位

// [manager stopUpdatingLocation];

//

//}

#pragma mark - MKReverseGeocoder delegate

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder

didFindPlacemark:(MKPlacemark *)place {

NSLog(@"---name,%@",place.name); // 位置名

NSLog(@"---thoroughfare,%@",place.thoroughfare); // 街道

NSLog(@"---subThoroughfare,%@",place.subThoroughfare); // 子街道

NSLog(@"---locality,%@",place.locality); // 市

NSLog(@"---subLocality,%@",place.subLocality); // 区

NSLog(@"---country,%@",place.country); // 国家
